http://s7.postimg.org/t2m09d0x7/portable_headphone_amplifier_circuit_diagram.gif This is the circuit diagram that i want to build for my headphone. The circuit shown is for the left channel only but i want to modify it a bit for a stereo version. Moreover, i want it to be powered by +5v from the laptop usb port. Can anyone help me out? Thank you.... This is the original link for the circuit diagram> http://www.learningelectronics.net/circuits/portable-headphone-amplifier-circuit.html
